摘要
讨论了在费米子动力学对称模型中大形变区核转动惯量的变化机制．指出在无Ｉ１带和基带交叉的情况下，ｈｅｒｉｔａｇｅ混合本身也可以引起转动惯量的变化，但引起混合的相互作用形式是重要的，引入某种三体相互作用后能很好地解释实验事实．
The mechanism of the variance of moment of inertia for well deformed nuclei in the Fermi Dynamical Symmetry Model is discussed.It is shown that without the crossing between I1 band and ground band,the heritage mixture itself also can cause the variance of nuclear moment of inertia.Nevertheless,the form of interaction is important,and the experimental data can be well reproduced by introducing three-body heritage mixing interaction.
